I understand the concept of electric field lines but don't understand the interaction with the equipotential lines. I understand that along each equipotential line/surface that there is no change in potential energy. I also understand the field lines need to cross perpendicularly with the equipotential lines. I don't know why though. Could anyone offer some insight on these equipotential lines. I really don't get why they're even there.
